Pro-Perfume Composition for Triggered Fragrance Release on Laundry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perfumery compositions face challenges with volatile perfumery raw materials that lack tenacity on laundry, leading to brief and weak perfuming effects, and require protection against degradation.
Innovation Solution
A perfuming composition comprising at least two pro-perfume compounds that release perfume compounds upon exposure to light, air/oxygen, heat, moisture, or enzymes, providing a controlled and prolonged fragrance release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If volatile perfumery raw materials are used, then fragrance intensity is improved, but fragrance longevity deteriorates
Solution Approach 1:
The patent applies preliminary action by using pro-perfume compounds that are pre-loaded with fragrance molecules in a bound state. These pro-perfumes are applied first and then gradually release the fragrance over time through environmental triggers, providing both initial fragrance presence and extended longevity without requiring continuous reapplication of volatile materials.
Solution Approach 2:
The patent changes the physical-chemical parameters of fragrance delivery by converting volatile perfumery raw materials into stable pro-perfume derivatives. These derivatives have different volatility and binding characteristics, allowing controlled release through parameter changes triggered by environmental factors such as moisture, heat, or pH changes on the skin or laundry.
2Quantity of substance
If standard perfumery raw materials are used, then fragrance deposition is improved, but tenacity on laundry deteriorates
Solution Approach 1:
The patent creates composite material systems by combining pro-perfume compounds with laundry care products. The pro-perfumes act as composite components that integrate fragrance functionality with laundry treatment, providing both deposition and tenacity through the combined properties of the composite system rather than relying on fragrance materials alone.
3Stability of the object's composition
If perfumery ingredients are protected against degradation, then stability is improved, but fragrance release efficiency deteriorates
Solution Approach 1:
The patent introduces pro-perfume compounds as intermediary substances that mediate between the stable bound state and the volatile fragrance state. These intermediaries protect the fragrance molecules during storage and application while providing controlled conversion to the active volatile form through environmental triggers, thus maintaining both stability and release efficiency.
